摘要：Methods that improve the learning performance of students in heterogeneous learning groups are constantly being sought after. The aim of the present study was to explore the possibility of using the smartphone to improve student classroom preparation. For this, a free app was used, which reminded the students on the content that needed to be learned and tasks that needed to be finished. This was done with the help of the devices that the students bring themselves (“Bring Your Own Device” - BYOD). The results of the study indicate a possible greater learning achievement by the users of the app when compared to the non-users. However, the use of the students' self-managed devices was also the cause of significant problems. These were identified through the use of log sheets which discovered the root cause of success or failure. The study was conducted in two eighth grade classes, with a total of 48 students from a middle school in the subject of chemistry. The study’s finding, that the use of reminder apps significantly raises learning outcome, is significant for chemistry lessons..
